* bug #1249: enable use of __builtin_prefetch for GCC, clang, and ICC only.Gravatar Gael Guennebaud2016-07-25

* Add TernaryFunctors and the betainc SpecialFunction.Gravatar Eugene Brevdo2016-06-02
| | | | | | | | | | | | | | | | | | | TernaryFunctors and their executors allow operations on 3-tuples of inputs. API fully implemented for Arrays and Tensors based on binary functors. Ported the cephes betainc function (regularized incomplete beta integral) to Eigen, with support for CPU and GPU, floats, doubles, and half types. Added unit tests in array.cpp and cxx11_tensor_cuda.cu Collapsed revision * Merged helper methods for betainc across floats and doubles. * Added TensorGlobalFunctions with betainc(). Removed betainc() from TensorBase. * Clean up CwiseTernaryOp checks, change igamma_helper to cephes_helper. * betainc: merge incbcf and incbd into incbeta_cfe. and more cleanup. * Update TernaryOp and SpecialFunctions (betainc) based on review comments.

* First part of a big refactoring of alignment control to enable the handling ↵Gravatar Gael Guennebaud2015-08-06
| | | | | | | | | of arbitrarily aligned buffers. It includes: - AlignedBit flag is deprecated. Alignment is now specified by the evaluator through the 'Alignment' enum, e.g., evaluator<Xpr>::Alignment. Its value is in Bytes. - Add several enums to specify alignment: Aligned8, Aligned16, Aligned32, Aligned64, Aligned128. AlignedMax corresponds to EIGEN_MAX_ALIGN_BYTES. Such enums are used to define the above Alignment value, and as the 'Options' template parameter of Map<> and Ref<>. - The Aligned enum is now deprecated. It is now an alias for Aligned16. - Currently, traits<Matrix<>>, traits<Array<>>, traits<Ref<>>, traits<Map<>>, and traits<Block<>> also expose the Alignment enum.

| * Replace a static assert by a runtime one, fixes the build of unit tests on ARMGravatar Benoit Jacob2015-02-27
|/ | | | | Also safely assert in the non-implemented path that should never be taken in practice, and would return wrong results.
* bug #955 - Implement a rotating kernel alternative in the 3px4 gebp pathGravatar Benoit Jacob2015-02-18
| | | | | | | | This is substantially faster on ARM, where it's important to minimize the number of loads. This is specific to the case where all packet types are of size 4. I made my best attempt to minimize how dirty this is... opinions welcome. Eventually one could have a generic rotated kernel, but it would take some work to get there. Also, on sandy bridge, in my experience, it's not beneficial (even about 1% slower).
